CVE-2012-4853
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedCross-site request forgery (CSRF) vulnerability in IBM WebSphere Application Server 6.1 before 6.1.0.45, 7.0 before 7.0.0.25, 8.0 before 8.0.0.5, and 8.5 before 8.5.0.1 allows remote attackers to hijack the authentication of arbitrary users for requests that trigger information disclosure.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceCross-site request forgery (CSRF) vulnerability in IBM WebSphere Application Server allows remote attackers to hijack authentication of arbitrary users for requests that trigger information disclosure.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify WebSphere Application Server installation path and versionRun the versionInfo command from the bin directory of the WebSphere installation (typically <WAS_HOME>/bin/versionInfo.sh or versionInfo.bat), or examine the product.properties file located in the <WAS_HOME>/properties directoryAffected if The displayed version falls within these vulnerable ranges: 6.1.x before 6.1.0.45, 7.0.x before 7.0.0.25, 8.0.x before 8.0.0.5, or 8.5.x before 8.5.0.1
-
Verify the exact fix pack levelFrom the versionInfo output, locate the 'Platform Version' and 'Build Level' fields. Confirm whether the installed fix pack (shown as 6.1.0.45, 7.0.0.25, 8.0.0.5, or 8.5.0.1) is below the fixed thresholds listedAffected if The fix pack number is lower than 45 for version 6.1, lower than 25 for version 7.0, lower than 5 for version 8.0, or lower than 1 for version 8.5
-
Confirm global security configurationAccess the WebSphere Administration Console, navigate to Security > Global Security, and check whether security is enabled. This vulnerability can be exploited only against authenticated sessionsAffected if Global security is enabled and the server runs a vulnerable version as identified in step 2
You are affected if your WebSphere Application Server version is 6.1.0.44 or earlier, 7.0.0.24 or earlier, 8.0.0.4 or earlier, or 8.5.0.0 (any 8.5 version before 8.5.0.1).
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply IBM's official patches by upgrading to WebSphere 6.1.0.45, 7.0.0.25, 8.0.0.5, or 8.5.0.1 or later respectively. Prior to patching, validate existing CSRF protections as a defense-in-depth measure.
